PHP多维数组合并数组中的两棵树如何？

我想将两棵树合并到php中md数组中的多维树中：

$array[1]=数组

            [0] => a
            [1] => b
            [2] => c

            [0] => d
            [1] => e
            [2] => f  

            [0] => ad
            [1] => be
            [2] => cf

$array[2]=数组

            [0] => a
            [1] => b
            [2] => c

            [0] => d
            [1] => e
            [2] => f  

            [0] => ad
            [1] => be
            [2] => cf

结果:

$array[1]=数组

            [0] => a
            [1] => b
            [2] => c

            [0] => d
            [1] => e
            [2] => f  

            [0] => ad
            [1] => be
            [2] => cf

你可以试试这个：

<?php

foreach($array[1] as $key => $value)
{
  $array[1][$key] = $value.$array[2][$key];
}

?>
